Titanium Ti hybrid double-H pipe + MPE (triple H setup)

[m3s65b4.x]

I personally don't like e9x stock x-pipe sound. Double x may be better but at first decided to go H-pipe. I have stock pipe modified to front H and rear x deleted. Way better and cleaner sound for me.
But stg2 tune needs some freeflow exhaust so i ordered titanium front and rear h pipes with SS cats. Gonna install and pair with MPE soon but atm Meistershaft GT, first sound clip i'll try to record will be w/Meistershaft.

X-pipe and front x may advantage top end power but i don't need top end, prefer low to middle acceleration and cleaner sound.

I would love to hear how this sounds!!! Have always wondered how a proper H setup would sound on the m3…

guess you never looked into the remus race pipe..

also.

that H cross over at the front is so poorly placed lol. that design is basically just pushing the gasses and colliding into each other.

the whole point of a H cross over, is to have the gasses "shave" into that central point to create a pocket of gas that then the other passing gasses bounce off of.. you might not get the results you want based on that.

I’ve only heard the remus on raspy setups with no cats or resonators, which was why I wanted to hear this
Interesting though…

Love when dudes post this stuff without videos.

Installed today so no videos yesterday..

Some pics and video clips now here. Didn't install MPE yet, left Meistershaft GT.
First impressions - sound is loud but I like it IRL, video sound not too accurate, i'll try record MPE triple H sound with other equipment later.

Year ago installed ebay SS pipe w/ primary cats, secondary deleted, rear resonators. That pipe sounded nasty and ugly. Now Ti pipe sounds miles better, definitely new and interesting sound.

New zyndspulen all 8, low mileage (3000km) O2 sensors, primary cats delete you feel immediatly how car pulls stronger, very quickly 100km/h in 2. gear, rear tires spins and you can drift. Anyway 100+HP for this car would be better.

Sounds raspy as hell. Not a fan.

Terrible crossover design as well. That front H connection looks like the two banks will be fighting each other rather than offer a scavenging effect.

You nailed, totally raspy, even over raspied. So project is dead and case is closed.
Don't try this at home.

Didn't left the project yet. Paired with M GT, SS race and MPE.

Meistershaft GT is loud and have some exotic Lamborghini like sound within 3-5k rpm at light accelerating but heavy raspy in flooring. There was thumbs up from people.

Supersprint Race is smoother and lil'bit less raspy but don't have exotic sound.

M Performance is louder than i expected but quieter than previous. Sound is better than SS but not like M GT.

Videos don't reflect the sound i hear in person (lack of splitter, cables and mics). Raspy but not too bad.
I'll delete first H soon but it seems if you delete primary cats you have already raspier setup. After that replace secondary cats with long resonators.

Stock pipe H-pipe is safety but you don't benefit from stg 2 tune.
So i'll keep going to find breathier and acceptable sound.

i find it hard to believe you didnt notice any rasp with the MPE 1/2 since the MPE is the most raspiest rear section with any xpipe haha
